Hi, so this is the first draft of the first SCP I feel confident enough to share.You can find it right here
I spent quite a long time on this one so far, and I call it. A glass to the past! I am not keeping that name it's just the working title.
My goal isn't to make an scp that's big dark and scary, but one that's deceptively simple in concept but is extremely complicated in execution. My goal is to add more and more experiment logs with more and more interesting results, but with a natural and realistic progression. An SCP just intriguing enough that people reading it would ask, "what would happen if I did x?" and be genuinely curious. The best stories in my opinion are the ones that stay in your mind and keep you questioning.

pre-approved research materials available to any personnel of Clearance level 2

The 'is' should be replaced with 'are' as it is referencing more than one thing.

Personnel accessing SCP-XXXX are required to be accompanied by Dr. Morris or a senior member of the research team approved by the site director.

You can redact that last part about it being approved by the site director. If they need to be accompanied by Dr. Morris or a senior member of the research team, we can assume it has already been approved by the site director beforehand.

When SCP-XXXX is located within visible range of a camera all attempts at taking a photo with a digital camera will result in an error, and the shutters of film cameras will jam. Film based video cameras also fail, possible due to how film is just a series of photos taken in rapid succession, but digital video can be taken.

This seems oddly convenient for the foundation, as this scip just so happens to not allow anything but video being taken of it. This is a huge inconsistency, as you reference that film video recorder can't work due to it similarities to a camera, and yet digital video works just fine, even thought it works the same way as the film video recorder.

Its second anomalous property occurs when a photograph is placed underneath the lens of SCP-XXXX, and its light is turned on, anyone currently looking through the lens at the picture will appear to be sucked through the lens of SCP-XXXX and into an alternate reality designated as SCP-XXXX-B.

This sentence does not roll off the tongue well. I would recommend splitting it into two sentences, or if you can, use a semicolon to give the reader a pause. The clinical tone also falters here, as "appear to be sucked through the lense" is too casual. A variation of that in a clinical tone would be "When a subject looks through the lens of SCP-XXXX, its anomalous property activates, instantaneously transporting the subject to another reality, designated SCP-XXXX-B."

Anything brought into SCP-XXXX-B from the outside world will not be effected by it's properties

The word effected does not belong here. The word affected should be put there, as it references an effect currently happening. The word effect is use to describe a certain event as a result of certain actions.

…intractable, un-intractable…

I believe you meant 'interactive' in both those words.

TEST LOGS

To be honest, these tests are not as interesting as I was anticipating. With the casual tone in place of a clinical one, the writing takes a jarring shift that can put off a lot of readers. The tests are also quite short, not leaving much to be desired. I would recommend lengthening these tests, and add some interesting points and events that occurred during these tests, as to keep the reader engaged and expand on the lore of the SCP and its anomalous properties.

ADDENDUM

I don't believe this should be labelled as an addendum, it would fit better as a research note from the previous tests, as it references them heavily. The note itself is confusing to read as well, with wording that makes no sense when compared to the rest of the article. For example the use of the phrase "at the moment of creation" makes no sense, as there was no mention of anything regarding manifestations or generated entities due to the properties of this SCP. I would rewrite this to make more coherent sense, and expand on the idea of using "false" photos with this item.

CONCLUSION

All in all, I don't think it will do well on the mainsite in its current state. The clinical tone is inconsistent, the wording leaves readers confused on what the article is trying to convey, and the idea seems unpolished. I would highly recommend placing this idea in the Ideas and Brainstorming Forum to help clean it up and make it stand out from other similar scips. Although, the forums tend to move rather slowly, and it can take up to a week to get multiple reviews. If you haven't already, I'd recommend trying the IRC chatroom for real-time feedback. Alternatively, you can message a staff member and ask them to direct chat attention to your thread.
